How do I delete my save data and start over? My brother grabbed hold of my 3DS when I wasn't looking, and I now have twice as many Pokedex entries, all named such travesties as Purkachurrr, Panpurrr, Durnspurrrrr, and Metapod (an Azuril, mind).
Since I was maybe only 20 minutes in, I think it might be best (for my sanity if nothing else), to just start the game over. But I can't find a way to start a new game! The main menu only lets me continue on the current save file.
Is there a way to handle this in game, or should I be deleting data from the main 3DS OS instead?
